SPECIFICATION forming part of Letters Patent No. 732,565, dated June 30,1903.

Application led March 4, 1903.

To all whom t may concern,.-

Beit known thatI, GEORGE HENRY KLE'MM, a citizen of the United States,and a resident cf Fowler; in the county of Otero and State of Colorado,have invented new and Improved Features of Construction for anInsertible Closure for Liquid-Receptacles, of which the following is afull, clear, and exact description.

The object of this invention i's to provide novel details ofconstruction for the closure of a liquid-package, such as a filledbottle or other receptacle having arneck, which will effectively preventthe refillingof the bottle after its contents havebeen removed.

rlhe invention consists in the novel construction and combinationofparts, as is here inafter described, and defined in the appendedclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar characters of reference indicate corresponding parts inall the iigures;

Figure l is a vertical sectional view of the invention applied'to abottleneck, showing details in closed adj ustment, the section beingsubstantially on the line 1 'lfin Fig. 4.

Fig. 2 is a similar view, but showing the bottle-neck inverted and partstherein adjusted to open a passage therethrough. Fig. 3 is a transversesectional view substantially on the line 3 3 in Fig. l.' Fig. 4 is anenlarged transverse sectional View substantially on vthe line 4 4 inFig. l. Fig. 5is a transverse sectional view substantially on the line 5`5 in Fig. 1, and Fig. 6 is asideview of the bottle-closure and of aclamping-ring therefor.

kIn the drawings that show the construction and application of theimprovement, A represents the neck of a bottle, and B the portion of thebody ofthe bottle from which said neck projects, these parts being ofany preferred size and formed of glass or other Asuitable maf terial.The neck A may with advantage be formed cylindrically andv havesufficient length to receive the improved closure, to-

gether with an ordinary cork C, the latter being inserted into the neckat its pouring end to seal the bottle and prevent an improper escape ofthe liquid contents when the bottle is inverted, the improvement beingdesigned serial no. 146,080. uit man only to seal the bottle from anintroduction of liquid and permitting the removal of the contents of thebottle when it is partly or entirely inverted, as will hereinafter bemore fully explained. Y

The body of the improved closure consists of a plurality of similarsegmental blocks formed ofglass or other suitable material. -As shownthere are three of such sections l0 provided. Each piece l0 isof alength proportioned to the length of the neck A, and on the side whichin service has contact with the interior Wall of the neck A is renderedconvex throughout its extent, the degree of convexity of the threepieces or sections l0 producing a cylindrical contour for theseclosure-sections when they are joined together edgewise.

To enable the proper assembling of the similar closure-sections l0, theside edges of each of said segments are sloped to give the block wedgeform, said converging side edges being on lines thatar'e radial from theaxial center of the cylinder formed when the closure-sections are heldtogether with their edges in contact, as indicated at at in Figs. 4 and5. A Each closuresection 1Q is similarly concaved at and near each endthereof, these Ycoucavities forming circularly-walled passages bc,respectively at the upper and lower 'ends of the closure-body whenthethree sec! tions lO are joined together.

Directly below the'upperconcavity b in each closure-section'lO aplurality of recesses d' are formed, which are spaced apart by thelongitudinally-extended ribs c, these ribs and recesses extendingtoa-point near the longitudinal center of fthe-closure-section, wherethe ribs extending to the cupped upper sur-- face of the iangeg, whichlatter is thus adapted to serve as a valve-seat when theclosure-sections 10 are joined together at their edges.

The ribs e at their upper ends equal in height that of the upper ends ofthe ribs e, and a short distance below the valve-seat g,

as at e2, the ribs e are reduced in height, thisreduction in height ofsaid ribs continuing to a concavity c in the upper surface of the defining-wall of the passage formed at c near the lower end of each section10, which affords a valve-seat when these closure-sections are joinedtogether to form a cylindrical hollow plug.

In the space between the main portions of the ribs e a globular valve 11is introduced and seats upon the valve-seat g when the assembledsections 10 of the closure are disposed upright, and it will be seenthat the ribs e form guides for the valve and that the recesses d affordpassages for liquid when the valve is removed from said valve-seat. Asimilar spherical valve 12 is introduced into the space below thevalve-seat g, that is defined by the ribs e and recesses d', said valveby its gravity falling upon the annular valveseat c when the closuredevice is upright.

In t-he exterior surface of the three closuresections 10 at an equaldistance from their upper ends a circumferential channel h is formed,and in the inner surface of the bottlc-neck A a similar channel h isproduced, these channels when positioned oppositely by a properinsertion of the assembled sections 10 within the bottle-neck aording anannular keeper-groove, wherein a circular spring 13 may be located. Thespring 13 may be of any preferred form in cross -secti0n. As shown, itis a flat strip of resilient material, which may be first placed in thechannel h to hold the closure-sections 10 loosely connected together andsubsequently be introduced within the mating channel h by the insertionof the sections 10 and the spring encircling the same within thebottle-neck until the spring comes opposite the channel h', whereuponthe spring by expansion enters the channel and is located partially ineach channel, whereby the closure-plug is secured in the bottle-neck.

To facilitate the assembling of the closuresections 10, a shallow recessis formed in one edge of each closure-section, and on the other edgethereof directly opposite said recess a corresponding tongue m isformed, these tongues and recesses, which are equally distant from theupper ends of closure-sections, being engaged-that is, a tongue willenter an opposite recess in an adjacent closure-section when thesections are placed together edgewise and have the channels 7L thereindisposed as a continuous circumferential groove. The end portions of theclosure-sections 10 below the lower valve-seat c are similarlychamfered, so as to bevel the inner edge toward the outer edge of thesame, and thus adapt the closure-plug to permit the unimpeded passage ofall liquid held in the bottle through the lower end of the passage cwhen the neck A is inverted.

To fix the closure-plugin position and prevent leakage between thesections 10, any suitable cement may be thinly spread on the edges ofsaid closure sections before the valves are placed therein, and a thincoating of cement may also be spread upon the exterior of the assembledsections 10, so that the liquid in the bottle cannot leak throughbetween joints in the plug or between it and the inner surface of thebottle-neck.

It will be seen that the parts of the improved closure-plug may bequickly and conveniently assembled and inserted in the neck of a filledbottle or other receptacle having a channeled neck adapted to receivesaid plug and be therein secured by the spring 13, as before explained,and the bottle be hermetically sealed by means of the cork C.

When a portion of or the entire contents of the bottle having theimprovement is to be removed, the cork C being displaced, an inclinationof the bottle-neck A slightly beyond a horizontal plane will cause thespherical valves 11 and 12 to roll on the ribs e e' toward the offsets band e2 in the ribs e e', and as the grooves d d extend farther upwardthan said offsetsit will be seenthat liquid flowing from the bottlethrough the passage c will traverse the grooves d and pass the valve 12,that rests on the offsets e2, into the grooves d, past the valve 11,that rests against the offsets b on the ribs e, and thence out of thebottleneck.

Upon restoring the bottle to an upright position the valves 11 and 12instantly resume their seated engagement with the valve-seats g and c',and thus prevent an introduction of liquid into the bottle, as it willbe evident that it will be practically impossible to hold both of thevalves 11 and 12 off of their seats and pour liquid past them into theneckA of the bottle.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. A closure-plu g fora receptacle, comprising aplurality of segmental sections, convex on outer surfaces and concave oninner sides, the edges of said sections contacting throughout theirlength, each section having a plu rality of longitudinal grooves, ribsspacing the grooves, a transverse concaved flange formed on the ribsbetween the ends thereof, providing a valve-seat, a like valve-seat atlower ends of the ribs, two spherical valves respectively held looselyby the ribs above the valve-seats, and offsets formed on the ribswhereon the valves contact when the closureplug is inverted.

2. The combination with a bottle-neck having an interior annularchannel, of a closureplug, comprising three segmental sections, convexon their outer surfaces and concave on their inner sides, thelongitudinal edges of IOO IIO

said sections having tongue-and-groove connection, and contactingthroughout their extent when the sections are together inserted z in thebottle-neck, an annular channel formed in the outer side of thesectional closure-plug, a bent spring engaging within the channel in theplug and in the bottle-neck, each closureplug having two sets oflongitudinally-disposed grooves, spaced apart by ribs, said ribs beingreduced in height near their upper ends,

to produce offsets, a transverse concavedy flange intervening the twosets of ribs and grooves, forming a valve-seat when the closure-sectionsare assembled, a similar valve-
